About These Birds
Belted Kingfisher
ミヤマカワセミは雌の方が雄よりも派手な色彩を持つという点でユニークで、赤褐色の腹帯が余分に加わっている。これらの騒々しい鳥は独特のガラガラとした鳴き声で縄張りを宣言する。重厚な嘴を使って河岸に最大2.4mもの深さの営巣穴を掘る。
Japanese White-eye
The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
